[1] Presentations
[1.a] The size of the window that displays an image resource is very small and is not preserved between calls. You have to resize every time we open the resource. As Fit in Windows Checkbox no scrollbars (not resize when zoom is is 100%), I would suggest:
[1.a.1] Adjust the size of the window according to the user's screen resolution (1/3 reduction), aligning the image at the top left of the window.
[1.a.2] Having control of the position of the image using a mouse icon four arrows drag the image to the desired position and remove the scroll bars, retaining the zoom slider.
[1.b] Hide Style Palette at the end of a presentation. Disable Ctrl + T (Style Palette) and enable key to display / hide Navigation Tool, especially for presentations that doesn't use scale map to fit fullscreen. Forget scroll bars.

[2] Style Palette
[2.a] Align respect to the first selected object.
[2.b] Allow match the separation (horizontal / vertical) even though the objects are not aligned.
